- Description: Direct anthropogenic impacts on vulnerable marine ecosystems are growing and require effective conservation measures. Integrating the cost impacts of conservation interventions and optimising the spatiotemporal scale of management interventions may improve cohesion between opposing marine users. This study aimed to integrate spatial and temporal models to advise dynamic penguin-fishery management plans in Algoa Bay, off Gqeberha, South Africa, that would maximise penguin foraging success while minimising the impact on the fishing industry. Determining the foraging locations important to breeding penguins is fundamental when understanding the relationship between fisheries and prey availability. Using Global Positioning System (GPS) data gathered from feeding trips of breeding African penguins between 2012 and 2017, and a hidden Markov model, three behavioural states (foraging, commuting, transitioning) were inferred and used as conservation targets in spatial prioritisation using the prioritizr package in R. The cost to the fishery was estimated using the catch of pelagic fish by the fishing industry between 2012 and 2015 as the proxy. The energetic cost to penguins was the distance they travelled from their breeding colony. Nine prioritisation scenarios, varying in levels of conservation for penguins, spatial cohesion and costs to fisheries, were developed using all year’s combined data to explore an ‘optimal’ closure configuration. The optimal closure was determined as an area which met the targets for penguin conservation, with a low cost to the fishery, close to the breeding colony and spatially clumped. The best solution from each scenario was isolated and the solution for the conservation target of 20% foraging habitat, 10% commuting habitat and 10% transitioning habitat and a boundary penalty of 0.01 (a dimensionless value that is used to reduce spatial fragmentation – increasing the value of the parameter signals that it is important to minimise the total exposed boundary of the prioritisation by favouring solutions where units are clumped together) was chosen as the optimal closure. This configuration was used as a static closure and applied to individual fishing seasons to estimate how the cost of a static closure design to the fishery would vary between seasons. Subsequently, a dynamic closure was designed using the same optimal configuration criteria every year, and the cost to the fishing industry was compared seasonally with the cost of a static closure. The cost to fisheries of dynamic closures was consistently lower than that of a static closure and the area required to meet the penguin feeding targets was drastically reduced. While dynamic closure scenarios show promise to minimise costs to the industry while meeting penguin conservation targets, these configurations were designed retrospectively with data collected after the end of the fishery seasons. For efficient management, the closures need to be designed by using data collected at an appropriate temporal scale. For that, the critical missing dimension to this study is the addition of real-time data on pelagic fish positions, areas of fishing intensity and sites of penguin foraging to create appropriate recommendations for up-to-date fishery exclusion zones. Therefore, the priority now is to explore methods of collecting real-time data on pelagic fish abundance, feeding behaviour of penguins at sea, site and mass of pelagic fishery catch, and using these data to delineate real-time, dynamic closures, coupled with a governance and management strategy that can implement dynamic closures. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2023

- Description: This dissertation examines the competitiveness of management consulting (MC) of small, medium, and micro enterprises (SMMEs) in serving state-owned enterprises (SOEs) in South Africa (SA). The research focused on the preparedness, scalability, and sustainability of MC SMMEs in addressing the strategic challenges faced by SOEs. The mixed-method approach combined self-administered interviews with management consultants and a comprehensive literature review. The qualitative research method allowed for an in-depth exploration of the factors influencing the competitiveness of MC SMMEs. The interviews revealed that MC SMMEs possess the necessary technical expertise and skills, yet they face hurdles related to scalability and sustainability inherent in SMMEs. These challenges include limited access to funding, inadequate marketing capacities, and delayed payment for services rendered. The study highlights that MC SMMEs can handle high-value projects for SOEs but they encounter difficulties within the SOE environment, which is marked by ethical concerns. It emphasises the importance of vigilance and maintaining discipline in service delivery to address these challenges. Additionally, the research provides practical recommendations for SOEs to support and facilitate the growth of MC SMMEs, enabling innovative solutions in their services. By evaluating the competitiveness of MC SMMEs in serving SOEs, this research contributes to understanding the MC industry landscape in SA. It aims to assist in strengthening the capabilities and credibility of local MC SMMEs, fostering their growth and sustainability. The findings offer valuable insights for policymakers, industry practitioners, and stakeholders seeking to enhance the role of MC SMMEs in driving economic growth and innovation within the context of SOEs. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2023

- Description: Colon cancer like any other cancer is a condition in which cells grow uncontrollably and may even spread to other regions of the body through metastasis. Colon cancer was ranked the second leading cause of cancer related deaths worldwide in 2018. Research to advance treatment of cancer keeps advancing daily, However, a big challenge is drug-induced side effects due to toxicity against normal body cells. Therefore, the development of controlled release technologies in conjunction with targeted drug delivery may provide a more efficient and less dangerous approach to overcome the limits of traditional chemotherapy. Including the creation of nanoscale delivery vehicles capable of directing the release of chemotherapeutic drugs into cancer cells only. This study aims to investigate p14 peptide that would specifically target colorectal cancer cells and not normal body cells to develop a targeted drug delivery system using gold nanoparticles. This study serves as a pilot study of the primary aim. To achieve this, the effect of the peptide p14 and peptide functionalized gold nanoparticles (p14-AuNP) on colon cancer cells (HT-29) and normal epithelial cells (KMST-6) was determined. Firstly, gold nanoparticles were chemically synthesised and then functionalized with p14 peptide through Polyethylene glycol. Then assessment of their effect through in vitro cytotoxicity assay (MTT) and gene expression analysis (RT-qPCR) was conducted. Nanoparticles’ synthesis and functionalization was performed and confirmed: In vitro cytotoxicity through MTT assay was successfully conducted and p14-AuNP showed toxicity against colon cancer cells and lesser toxicity towards normal cells as compared to 5-Flourouracil (commercially approved drug for colon cancer treatment). Gene expression analysis revealed that apoptosis was induced in both cell lines by p14-AuNP either through upregulation of caspase 3, 7 and/or BCL2. A cell survival gene, AKT1, also had significant effect on this. CDC42 was downregulated which indicates that cell proliferation was inhibited. , Thesis (MSc) -- Faculty of Science, School of Biomolecular & Chemical Sciences, 2023

- Description: The seasonal and interannual variability of the coastal Benguela upwelling system is described using 22 years (September 1993 - December 2014) of a regional Ocean model (ROMS) output. The model-derived SSTs are evaluated against satellite SSTs (GHRSST) and biases between the datasets investigated, allowing for confidence in using the ROMS data to investigate details of spatial and temporal variability over the Benguela System. Variability of coastal SSTs are investigated together with alongshore winds (from the ERA-Interim Reanalysis product). The driver of the seasonality in upwelling in the Benguela region is the seasonal shift of the South Atlantic High pressure system, leading to an enhanced seasonal signal in the southern Benguela (with strongest upwelling favourable winds in austral spring and summer). In the northern Benguela, the seasonal signal reduces with the peak of upwelling favourable winds shifting to late winter and spring. Interannual variability is evident in the model and is investigated with respect to various modes of climate variability. Though the direct relationship of the Benguela upwelling system to large-scale climate modes such as SAM and ENSO is not clear in most places, some evidence was found for their connection. For instance, in the southernmost cell of the southern Benguela a significant positive and negative correlation exists between SST and wind respectively with ENSO during summer months. This relates to increased (decreased) winds and decreased (increased) SST during La Niña (El Niño) events. Although there was no direct correlation with either SST or alongshore wind anywhere in the Benguela system, there was some indication of its importance. A trend toward a positive SAM (i.e a more poleward position of the South Atlantic High-Pressure system) was consistent with a trend toward enhanced winds and reduced SSTs in the southernmost upwelling cell. In addition to this, there was evidence to suggest that when SAM and ENSO are out-of-phase, which occurred primarily during summer months, the wind and SST response is amplified. This seemed to be particularly true in the first 10 years of the timeseries when the anomalies were strongly alternating. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2023

- Description: The study is an instrumental case study of Isadora Duncan (1877 - 1927). She was a pioneer of modern dance as she developed her unique style of dance that was free-flowing and natural. She further developed her own dance philosophy, which drew the attention of many as its archetypal dancer was a woman who embodied a space that was equal and free. She was not only revolutionary in her unique dance style but also for her strong beliefs. Isadora Duncan believed in anti-marriage, bearing children out of wedlock, and fighting for the emancipation of women where she used dance, her philosophy and post-performance lectures to communicate her thoughts and beliefs. An Instrumental case study is a qualitative method of enquiry, which entails researching an event or individual as a means of providing or gaining insight into a particular phenomenon. Similar to that of a psychobiography, the individual subject can be explored through the lens of a psychological theory for the purpose of creating a coherent psychological case study. The psychoanalytical lens of Carl Jung was used to explore and describe certain aspects of the life and work of Isadora Duncan. The subfield of the Psychology of Women provides a contextual description for the challenges that women faced in the past and in the present, and additionally presents the primary aim of the proposed study. Isadora Duncan was chosen due to her unique dance movement, both literally and figuratively as she developed her ability in giving voice to those emotions that women often kept hidden. She lived during significant times which included radical transformations that brought about noticeable change politically, socially, and culturally. Despite the reformative motions, it did not dismiss its own challenges especially for women. Women faced a constant struggle for freedom from oppression, community rights and gender equality, and Isadora Duncan was no exception to these challenges. Extensive biographical information data was collected and processed into salient features. The study integrates the theory of Carl Jung, the life and dance philosophy of Isadora Duncan and the v challenges faced by women over the centuries and demonstrates the value of using an instrumental case study as a method of inquiry into the exploration of a unique individual. The Psychology of Women provides an understanding of how those past challenges may still be modern-day concerns for the psychology of women today. The findings of the study demonstrated that Isadora Duncan was a unique and innovate women who pushed the boundaries socially. She was determined to perform her unique dance style in times that required women to conform to the cultural expectations. However, in times of trouble and despair, she was able to turn to dance as the individual and collective voice. The contribution of the study rests with its demonstration of the value of a holistic and reflexive exploration of a unique individual woman. It demonstrates the value and application of Jung’s in-depth theoretical understanding of the archetypes in human behaviour and the use of dance as a healing process for psychologically wounded women. Therefore, specific reference to the true inner voice of women allows insight into how clinicians might assist female clients who struggle to release their true inner voice. Furthermore, the study contributes to building knowledge of the challenges that women face in society and allows for future research of exploring integrative theoretical frameworks in understanding the healing of psychologically fragmented women in the 21st century. , Thesis (Ma) -- Faculty of Health Science, 2023

- Description: Background: Workers accidents at work have been demonstrated to be increasingly common and expensive, particularly in developing nations like South Africa. The failure of employers and employees to support and comply to (OHS) regulations measures frequently leads to injuries and accidents that are extremely expensive for both the employer and employees. Regardless of South African legislations that aim to prevent accidents and injuries, scourging statistics of industrial accidents are still a characteristic of OHS. Objectives: This study investigates knowledge gaps, attitude, and the practice of municipal workers regarding OHS at Garden Route District Municipality (GRDM) in the Western Cape Province of South Africa. Methodology: Quantitative approach was taken, and questionnaires were administered to 188 workers employed by the GRDM. A probability sampling method of stratified sampling method was utilised. Results: This study concluded that the workers of the GRDM are knowledgeable about OHS in their workplaces and that municipal workers positively perceive OHS issues in their workplaces. The main reason for this positive perception is because of the management support that the workers receive from the GRDM with regards to OHS matters. Furthermore most workers positively perceived OHS protocols and measures undertaken at the GRDM. Statistical tests proved that the municipal workers who positively perceived OHS protocols and measures were significantly higher (p< 0.05) than those that negatively perceived OHS protocols. Conclusion: The study revealed that GRDM workers were knowledgeable on OHS protocols. This was because of the support that they get from their employer as well as personal health and safety concerns. They positively perceived the OSH measures that are put in place to prevent accidents and injuries. It is only an insignificant percentage of individuals that disagreed with some of the OHS measures and protocols. This study contributes immeasurably to academic research in the field of OHS and extends knowledge that relates workers’ perceptions, safety awareness, as well as workers’ adherence to safety and behaviour. , Thesis (Ma) -- Faculty of Health Science, 2023

- Description: The emergence of social media (SM) in the academic arena has demonstrated the potential for innovation in teaching and learning. Moreover, its appeal is enhanced by its accessibility and affordability. Consequently, the use of SM has increased globally and has influenced interaction and socialisation amongst educators and learners. In addition, SM has affected learning and how educators teach and collaborate with learners when constructing knowledge in higher education settings. However, despite its advantages, nurse educators' use of SM is less than optimal in teaching. Therefore, the study aimed to explore nurse educators' knowledge, attitudes and practices regarding the use of SM as a teaching strategy at a public nursing college in the province of Limpopo, South Africa. The research design employed for this study was quantitative, explorative, descriptive and contextual, and Roger’s diffusion of innovation theory underpinned the study. Stratified, proportionate sampling was used to select the nurse educators who were respondents to the study’s survey via a questionnaire as the data collection instrument. An educator as a specialist in the use of SM, a statistician and the study supervisors reviewed the questionnaire. A pilot study was conducted to check the validity and reliability of the data collection instrument. Data gathered through the survey was statistically analysed to produce descriptive statistics. The researcher adhered to the ethical principles of respect, beneficence, and justice. The research results indicated that the nurse educators in the study were knowledgeable about SM platforms. Moreover, although they had a positive attitude towards incorporating SM as a teaching strategy. Therefore, based on the research results, recommendations were to facilitate the use of SM as a teaching strategy. , Thesis (Ma) -- Faculty of Health Science, 2023

- Description: The emergence of social media (SM) in the academic arena has demonstrated the potential for innovation in teaching and learning. Moreover, its appeal is enhanced by its accessibility and affordability. Consequently, the use of SM has increased globally and has influenced interaction and socialisation amongst educators and learners. In addition, SM has affected learning and how educators teach and collaborate with learners when constructing knowledge in higher education settings. However, despite its advantages, nurse educators' use of SM is less than optimal in teaching. Therefore, the study aimed to explore nurse educators' knowledge, attitudes and practices regarding the use of SM as a teaching strategy at a public nursing college in the province of Limpopo, South Africa. The research design employed for this study was quantitative, explorative, descriptive and contextual, and Roger’s diffusion of innovation theory underpinned the study.

- Description: The provision of services to people in South Africa is a constitutional right that all spheres of the South African government are bound to. South Africa’s Bill of Rights also lays it out that all SA citizens are entitled to these services. The functions of the national, provincial, and local spheres of government are to ensure that all that the Constitution and Bill of Rights promise, are provided and implemented. Service delivery is therefore a mandated activity that all municipalities are obligated to provide to their residents locally. The primary objective of this study is to assess the quality of the service delivery effort from the Nelson Mandela Bay Municipality (NMBM). The study was conducted by using a qualitative case study approach. A total of 12 participants were chosen for the study and in-depth interviews were implemented as data collection tool to accomplish the study’s objectives. The qualitative data analysis tool Atlas.ti was employed to present emerging themes from the collected data. The findings of the study highlighted the challenges experienced in the NMBM prevent a high level of service delivery to residents. The study participants agreed that the service delivery effort in the NMBM is below that what the various stakeholders, mainly the residents, expected. The effective management of the limited financial and human resources are the major themes that emerged during the interviews. The study recommends that the service delivery value chain be reviewed, and that policies and strategies be genuinely implemented. The study also suggests that proactive communication with residents be improved. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2023

- Description: The present research aimed at investigating mechanical recyclability and studying the potential biotic and abiotic degradation behaviors of biobased biodegradable polymers in different environmental conditions. The mechanical recyclability tests monitored the effect of multiple reprocessing on the mechanical, thermal, physical, chemical, and morphological properties of poly (butylene adipate-co-terephthalate) (PBAT), poly (butylene succinate) (PBS), poly (lactic acid) (PLA), PBAT-PBS blend, and PBAT-thermoplastic starch (TPS) composite. Low-density polyethylene (LDPE), a conventional non-biodegradable plastic, was also monitored for comparison studies. The mechanical recyclability tests were carried out by eight melt extrusion cycles using twin-screw extrusion and injection molding processing techniques. Tensile testing, impact analysis, melt flow index test (MFI), differential scanning calorimetry (DSC), thermogravimetry (TGA), dynamic mechanical analysis (DMA), Fourier Transform Infrared Spectroscopy (FTIR) and scanning electron microscopy (SEM) techniques were employed to monitor the effect mechanical recycling at each melt extrusion cycle. Tensile and impact strength results showed that PBAT and PBAT-TPS biocomposite were mechanical recyclable for at least eight cycles and this was comparable to LDPE recyclability performance. In contrast, neat PBS, PLA, and PBAT-PBS blend were found to be melt extrudable only up to six cycles as the mechanical properties declined with the increase of reprocessing cycles. MFI tests suggest that molecular weight of PBAT and PBAT-TPS were not significantly affected by multiple extrusion cycles while the melt flow properties of PBS, PLA, and PBAT-PBS samples were affected from third cycle. DSC, TGA, and DMA demonstrated that PBAT and PBAT-TPS were more thermo-mechanically stable than PBS, PLA, and PBAT-PBS blend. FTIR spectroscopy results showed that the chemical structure of both PBAT and PBAT-TPS were unaffected by the multiple recycling cycles typically indicated by characteristic peak vibrations bands of C=O and C-O around 1710 cm-1 and 1046-1100 cm-1, respectively. SEM micrographs of PBS, PLA, and PBAT-PBS clearly evidenced the degradation of the biopolymers by severely fractured morphology as a result multiple reprocessing cycle.The rate of aerobic biodegradation for PBAT-PBS and PBAT-PLA blends was examined under controlled home and industrial composting using the CO2 evolution respirometric method. FTIR, DSC, TGA, X-ray diffraction analysis (XRD), and SEM were employed to monitor the changes in the structural, chemical, thermal, and morphological characteristics of the biopolymer blends before and after biodegradation. The biodegradation tests showed that PBAT-PBS and PBAT-PLA blends exhibited higher degradation rates under industrial composting conditions than under home composting conditions. The increased intensity of hydroxyl and carbonyl absorption bands on the FTIR spectra confirmed that the biodegradation process occurred. SEM revealed that there was microbial colony formation and disintegration on the surfaces of the biopolymer blends. Moreover, abiotic degradation results suggested that thermal and hydrolytic conditions influence the degradation process than sunlight exposure. Additionally, aquatic biodegradation results showed that PBAT-PBS blend and PBAT-TPS composite undergo a higher rate of biodegradation as compared to PBAT, PBS, and PLA.The results obtained from this research work conclude that biobased biodegradable polymers can be mechanically recycled, and they are suitable for biological degradation in industrial composting, home composting and marine environment. , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2023

- Description: This treatise explores the critical factors affecting digital literacy within a South African Automotive Manufacturer. Previous research conducted within the organisation revealed that employees were not using digital tools to its full potential, and according to the literature, digital capabilities are one of the main drivers for organisational agility. There is a lack of research on digital literacy and organisational agility in a South African automotive context. As technology progresses rapidly, organisations must innovate to remain agile and relevant. This qualitative research study was conducted through a constructivist worldview, allowing the researcher and participant an opportunity to interact during an interview session to uncover experiences and thoughts relating to digital literacy within the organisation. The study enrolled 14 participants, and this was sufficient to achieve meaningful saturation of the data. The study highlighted low confidence levels in technology adoption within the organisation, often causing anxiety and apprehension among employees. This psychological barrier stems from a lack of digital literacy skills underpinned by insufficient training to fully understand the benefits technology may provide to the user and the organisation. The lack of awareness may be linked to ineffective communication techniques the organisation employs when relaying training or information relating to available resources. Furthermore, to enhance digital literacy skills, the study found that individuals need to have good foundational knowledge from which to build and have supportive leadership that assists in acquiring the necessary resources and training. This study provides insights into digital literacy within a South African Automotive Manufacturer. It will allow management to develop strategies to improve digital literacy levels and establish a learning culture where employees have higher levels of self-efficacy. When an organisation embraces digital technology, it increases productivity and fosters innovation. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2023

- Description: Daisy Louisa C. de Melker, born on 1 June 1886, was a qualified nurse who is famously known to have poisoned two husbands with strychnine in order to receive life insurance money while living in Turffontein, Johannesburg. Later on, she poisoned her only son with arsenic for reasons which are still unclear, and he passed away soon after. She is notoriously known in history to be the second woman to have been hanged in South Africa due to receiving the death penalty. The primary aim of the study is to explore the life of de Melker to gain an understanding of her personality development, with the aim of acquiring insight into the motivation behind her behaviour. The secondary aim includes exploring apparent Cluster B personality traits. The study is exploratory-descriptive in nature and the subject was chosen through purposive sampling. The study uses a qualitative, psycho-biographical, single-case research design to study De Melker, in order to explore and describe the personality development of her from the theoretical perspectives of Kernberg’s Object Relations Theory. This specific theory was chosen as it allowed the researcher to explore Daisy de Melker’s early childhood and upbringing that impacted the formation of ‘internal representations’ of herself and other people. The theory suggests that when there is a lack of integration of object relations, which is made up of internal and external representations, it may result in the development of a personality disorder, as it places a focus on relationships being more crucial to personality development than individual drives and abilities. Data was collected by triangulating multiple sources of information. Miles and Huberman’s (1994) strategy were used to analyse the data according to three steps, which include data reduction, data display, and conclusion drawing and verification. The significance of doing a psychobiography study lies in merging of personality psychology and historical evidence which represents a growing field in the realm of biography and provides insight into personality development through a theoretical framework. , Thesis (Ma) -- Faculty of Health Science. 2023

- Description: Human-wildlife conflict (HWC) is a prevailing issue worldwide, threatening the livelihood of the affected human communities, and the persistence of wildlife populations and habitat. Human-elephant conflict (HEC) is particularly challenging, given the damage or harm these large animals can cause to human communities. Moreover, HEC threatens the safety of elephant populations as elephants can be injured or killed when people retaliate. Several studies have therefore been conducted to investigate HEC spatiotemporal patterns in order to better understand it and to develop mitigation measures. These studies predominantly used non-spatial statistics or global regressions to investigate HEC patterns and drivers. The general understanding of HEC patterns and drivers are therefore based on general predictions derived from global regressions that assume stationarity of the relationship between HEC and its drivers across the landscape. Previous studies using global regressions may therefore have missed or misidentified important drivers of the spatial patterns, making the resultant global regression models misleading. The aim of this study was therefore to investigate the spatiotemporal patterns and drivers of HEC adjacent to Liwonde National Park using spatial analytical tools that account for the spatial nature of the data and the spatial variation in conflict drivers across a landscape. Using a Geographically Weighted Regression, I identified vegetation quality, season, and distance to seasonal water as drivers of HEC hotspots adjacent to Liwonde. HEC was more intense in areas with higher quality vegetation (compared to vegetation quality inside the Park) and areas that were closer to seasonal water. The relationship between HEC hotspots and these drivers varied at the patch-level and according to season. My findings suggest that HEC is more complex than the general patterns described with global regressions. The localized patterns and drivers of HEC hotspots identified, reflect trade-off between elephants securing rewards (crops), while reducing risks (encountering humans), as expected under forage optimality models. The understanding of elephant adaptation and trade-offs in human landscapes gained from my study, along with the approach I have adopted, can be applied to other HEC study sites, and help guide HEC management in Liwonde. This approach can also be applied to analysis of other forms of HWC, greatly improving HWC mitigation. , Thesis (MSc) -- Faculty of Science, School of Natural Resource Management, 2023

- Description: Knowledge surrounding the procedures and protocols related to groundwater sampling are currently limited. In particular, the sampling of radioactive elements from fractured rock aquifers is poorly understood and in need of further research. The aim of this study is to provide a comparative insight into groundwater sampling methods used for the sampling of major and minor elements as well as trace elements within fractured rock aquifers in the immediate vicinity of Beaufort West. The influence of sampling source, seasonality, and vertical flows on sample results are observed. Furthermore, the importance of historical datasets is raised. Aims of this study were achieved by making use of historical data from numerous studies that were conducted near the Karoo town of Beaufort West. Potential profitable uranium deposits saw a great influx of research into the geology, topography, climate and hydrogeology. Synthesising data from these historical research papers has provided valuable information regarding the influences of sampling procedures on the results. A total of 695 well data samples were analysed from four studies collected from farms around Beaufort West. The importance of adequately purging a well prior to sampling cannot be stressed enough. There are minimal chemical differences between sampling boreholes and wind pumps, however there was a noticeable difference in the inter-relationships between major chemical elements. Groundwater samplers were found to be contaminated with Zinc and Copper attributed to wind pump fittings. Boreholes were also analysed to observe any changes in depth. Sodium, temperature and uranium had little to no changes with depth due to the homogenous nature of the borehole water. Principal component analysis was conducted on 159 groundwater samples comprised of 13 variables. These samples were reduced to four principal components (PC) which explained a total of 91.09% of the total variance. Factor one explained 61.99% of the total variance and was strongly associated with water-type and lithology while factor two (13.57%) shows the potential relationship between molybdenum and uranium as well as possible copper contamination as a result of wind pump and borehole fittings. Further research should be conducted by carrying out multiple sampling procedures on a selection of controlled wells to determine the best applicable sampling procedures. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2023

- Description: The automotive retail industry in South Africa is a significant contributor to the country's economy, and the role of technicians in the industry is critical for the industry's growth and sustainability. However, the industry is faced with a shortage of skilled technicians, resulting in a skills gap that threatens the industry's progress. This study therefore aimed to identify the strategies that can be used to promote the skills development of technicians for the automotive retail industry. A qualitative research design was used, and data was collected through semi-structured interviews with stakeholders in the automotive retail industry. The data was analysed using thematic analysis. The findings of the study revealed that the industry faces several challenges, including the lack of funding for skills development programmes, inadequate training facilities, and an outdated curriculum. To address these challenges, the study recommends that the industry should adopt a multi-stakeholder approach that involves government, industry and training institutions. The study also recommends that the government needs to provide funding for skills development programmes and create policies that promote the training of technicians. The industry should work with institutions such as technical and non-technical high schools, TVET colleges, and universities to develop a relevant curriculum that is aligned with industry needs. The study further recommends that the industry should create partnerships with Original Equipment Manufacturers (OEMs) to provide training opportunities for technicians. In conclusion, the automotive retail industry in South Africa needs to invest in the skills development of technicians to address the skills gap and promote the industry's growth and sustainability. The adoption of a multi-stakeholder approach involving government, industry, and training institutions is essential for the success of skills development programmes in the industry. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Management Sciences, 2023

- Description: School safety is regarded as one of the key drivers of quality teaching and learning. There is however evidence that schools worldwide experience violence and learner disruptive behaviours. The South African education system is amongst other areas, focusing on gender equity in leadership and management positions. Hence this paper explored the strategies used by female principals to manage learner discipline in selected primary schools in the Buffalo City Education District. The Complexity Leadership Theory underpinned the study in conjunction with the Intersectionality theory. Complexity Leadership Theory emphasises the identification and exploration of strategies and behaviour that nurture creativity, learning, and adaptability in the organisation. Data were collected from fourteen participants ranging from female principals, HOD and Vice Principals. Interpretive qualitative and descriptive case study design was used. Data were collected through the use of one-on-one semi-structured interviews, and document review was the second research instrument used in this study. Thematic analysis was used to analyse data and all ethical issues were observed. The participation of participants was voluntary, and anonymity was guaranteed. Some of the major findings were the participants’ use of their gender (female) as a resource in administering discipline, and their awareness and consciousness of the vulnerability of the school context. Parental involvement, community involvement and closed-circuit television (CCTV) camera systems aided the participants in maintaining learner discipline. Rewarding learners for good behaviour or good work habits (behaviourism) was discouraged due to its inability to intrinsically motivate learners to behave and accomplish goals. Instead, it was reported to be a form of a bribery system which teaches learners to work hard to receive something. The findings suggested that tertiary institutions introduce mandatory counselling courses to equip prospective teachers with necessary skills to effectively deal with issues of learner discipline in schools. , Thesis (MEd) -- Faculty of Education, 2023

- Description: Generally, the elders in the family are usually responsible for their families, including the care and socialisation of younger members. With the increasing number of mental illness cases being reported, not only in South Africa but the rest of the world, it is imperative to explore what the elderly understand about mental illnesses, given that they may have insights that might be useful. This study aimed to explore the perceptions of elderly members in the isiXhosa community of the Buffalo City Metropolitan Municipality in the Eastern Cape province, regarding their understanding of mental illnesses. The researcher employed an exploratory-descriptive, qualitative design and adopted Lincoln and Guba’s model of trustworthiness. Participants were recruited through the use of snowball and purposive sampling and the data was gathered through one-on-one interviews conducted with elderly isiXhosa individuals. Thematic analysis was used as a means of data analysis, by following data analysis method by Braun and Clarke. The following themes were identified during the study; Limited understanding about mental illness, varied causes of mental illness and a generationally linked understanding of mental illness. The findings reflected the participants understanding of what mental illness is and the causes of it and suggest that more research is required to understand the cultural influences on perceptions of mental illness. , Thesis (Ma) -- Faculty of Health Science, 2023

- Description: The working landscape underwent significant changes due to the Covid-19 pandemic, leading to an increased need for employees to enhance their self-leadership skills. The advancement of these skills could assist individuals to adapt and thrive in the face of relentless change. While self-leadership skills have traditionally been cultivated through training, coaching research has typically not considered it as a process of contributing to the growth of self-leadership. This study aims to explore the contribution of generic coaching to self-leadership. A qualitative research design using a purposive sampling method was applied to a sample group consisting of nine coachees. Coaches from the researcher’s network in South Africa had referred coachees who had previously been engaged in an individual generic coaching process, such as life, health, career, business or executive coaching. This exploratory study involved conducting semi-structured online interviews to collect data. An interpretative phenomenological analysis was adopted to learn about the lived coaching experiences of the participants. A thematic analysis approach was applied to the data to extract repeated themes that could provide answers to the research questions. The themes that emerged from the data included (1) the generic coaching process, (2) the factors that facilitate effective coaching, (3) the impact of coaching, and (4) the understanding of self-leadership. The findings of the research had, to a large extent, indicated that generic coaching contributed to self-leadership. The connection between the three self-leadership strategies, the coaching process and the tools that were used made this apparent. Coaching is another method of development that can enhance employees’ self-leadership skills, accelerate growth and facilitate learning. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Industrial Psychology and Human Resources, 2023

- Description: The study investigated the contribution of women to household food security in Makholokoeng village and Diyatalawa village, Free State Province. Women’s contribution to household food security is poorly documented and misunderstood. Most often women’s contribution is considered as part of the duties of women as a wife and mother than as an occupation to be vaunted for both the household and national economy. Women play crucial roles in household food security as food producers, processors, and food providers for their families. Despite these crucial roles women remain unrecognised as main contributors of household food security. The study was guided by pragmatic research philosophy that used Participatory Rural Appraisal tool amongst other data collection tools to answer the objectives of the study. The study findings show that there is a clear-cut of the agricultural roles men and women perform in agriculture but the involvement of women in decision-making varies with crops and the type of household. The contribution of women to household food security is evident. However, women continue to face challenges which are limiting the role of women in household food security. The study recommends that further studies should be conducted to investigate gender roles in agriculture; and the effectiveness of gender equality policy implementation in agricultural initiatives. , Thesis (MA) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2023

- Description: COVID-19 increased in prevalence in 2019 and was declared a pandemic in 2020 by the World Health Organisation (WHO). The pandemic arrived in South Africa in March 2020, and drastically impacted the country. One such impact was to healthcare workers, who had contact with COVID-19 patients on an ongoing basis. Increasing pressure was placed on healthcare workers, and they needed to cope with the demands placed on them during the pandemic. The study aimed to explore and describe the coping experiences of healthcare workers during the COVID-19 pandemic in the Nelson Mandela Bay Health District. To meet this aim, a qualitative explorative descriptive research design was used. Data was collected using individual, semi-structured interviews, with a sample of 10 healthcare workers in the Nelson Mandela Bay Health District. The data was analysed using Braun and Clarke’s (2006) Reflexive Thematic Analysis and the trustworthiness of the study was ensured through Guba’s (1985) model of data verification. Social Constructionism was used as a theoretical framework to conceptualise the findings that emerged from the participants within their socio-historical context. Participants shared their coping experiences which were different from the other but shared particular themes. Participants made use a combination of problem, emotion and meaning focused coping strategies during the peaks while utilising predominantly problem focused coping strategies during the lulls. It became apparent that there were differences in coping in terms of the lulls and the peaks with peaks producing fear and anxiety, while lulls bringing a sense of relief. , Thesis (Ma) -- Faculty of Health Science, 2023

- Description: The COVID-19 pandemic disrupted the global economy and work methods, highlighting Human Resources limitations. This study explores its lasting impact on the future of work in South Africa, focusing on employee engagement, mental health, burnout, work quality, and future of work expectations. To provide a comprehensive understanding of the subject, an extensive literature review was conducted, including academic articles, industry reports, and publications, to examine pandemic effects on work practices, remote work, HR strategies, employee engagement, mental health, burnout, and future work expectations. Building upon the insights that were gained from the literature review, an online survey was designed, consisting of 70 closed-ended questions. The survey sought to capture respondents’ perceptions of work before and during the pandemic, as well as their expectations for the future of work considering the observed emerging trends during the crisis. The survey link was distributed to a sample of 130 respondents using a web-based survey approach. Of the targeted population, 51% completed the survey, thereby resulting in a final study sample of 66 respondents. Subsequently, a conceptual model was developed to illustrate the long-term impact of the COVID-19 pandemic on the future of work in South Africa. The collected data was subjected to rigorous statistical analysis by employing various techniques such as the data spread analysis, summary statistics, data variation measures, internal consistency analysis, linear correlation, and factor analysis. The Exploratory Factor Analysis (EFA) was employed to ensure the validity of the measurement constructs and to ascertain the items that required removal. These statistical analyses provided an empirical evaluation of the impact of COVID-19 on employee engagement, mental health, burnout, and future work expectations. The results of the data analysis confirmed the hypothesised model, thereby indicating that all the four independent variables exerted a significant influence on the future of work in South Africa. The factors such as work engagement, work immersion, personal and professional burnout, client-related burnout, work environment, relations and cooperation, autonomy, facilities, work-life balance, work flexibility, leadership, and remote well-being were measured to assess this influence. Work burnout during the COVID-19 period was omitted from the analysis due to its failure to meet the minimum EFA loading criteria for the factor. In addition to the empirical findings, a framework for managing the future of work was designed based on the research outcomes. The study also discussed the encountered limitations, as well as called for further research in the field. It also provided recommendations for the HR professionals, the leaders, and the employees. Implementing these recommendations would enable the organisations to navigate the future world of work more successfully, which would foster greater agility and sustainability. These measures are fundamental in creating adaptable workplace models, strategies, and policies that respond adeptly to the dynamic shifts in the internal and the external contexts. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2023
